    description: |
      ADC settling time in ADC clock cycles. When the gain, offset
      or differential input parameters of the analog cell change
      between two channels, the analog cell may need a specific
      settling time before starting the tracking phase.

    required: true
    description: |
      ADC tracking time in ADC clock cycles. A minimal tracking time
      is necessary for the ADC to guarantee the best converted final
      value between two channel selections.
